Mr. Food: Roasted Holiday Prime Rib


What You’ll Need

  • 1 (5- to 6-pound) boneless beef prime rib
  • 3 tablespoons all-purpose flour
  • 2 tablespoons vegetable oil
  • 1 tablespoon Dijon mustard
  • 1 tablespoon light brown sugar
  • 1/2 teaspoon ground allspice
  • 1 teaspoon salt
  • 1 teaspoon black pepper

What to Do

  1. Preheat oven to 400 degrees F. Coat roasting pan with cooking spray. Place beef fat side up in pan.
  2. In a small bowl, combine remaining ingredients; mix well. Rub mixture evenly over beef. The mixture will be kind of thick, so you will need to sort of pat it on.
  3. Roast beef 20 minutes, then reduce heat to 325 degrees. Continue cooking 1-1/4 to 1-1/2 hours (or about 15 minutes per pound), or until a meat thermometer reaches 135 degrees for medium-rare, or until desired doneness beyond that. (Even though medium rare is 145 degrees, the meat will continue to cook once you take it out of the oven, so after it rests for about 10 minutes, it should be perfect.)
  4. Remove beef to cutting board and let stand 15 minutes before carving into thick slices.
